1 '0 all whom it may concern:

Be it known that I, LOUIS A. Oseoon, a citizen of the United States,residing at Springfield, inthe county of Clark and State of Ohio, haveinvented certain new and useful Improvements in Automatic Weighing-Scales, of which the following is a specification.

This invention relates to improvements in weighing machines, andparticularly -in making the mechanism compact, simple in itsconstruction and efficient for its purpose.

Referring to the drawings, Figure 1 is a front elevation of the machine,Figs. 2 and 3. are detail views of parts of the machine; Figs. 1 and 5are sectional views of the pinion shaft and its bearings, and the cagesupporting shaft; Figs. 6, 7 and 8 are details of parts of the indicatorand its supporting mechanism.

Like letters of reference indicate like parts throughout the differentviews.

The improvements relate more particu larlyto the type of machine knownas the dial-pendulum scale, and there is illustrated herein a pendulumscale, employing an elon-' gated load supporting member, having the,

This rod is attached in the usual way at its upper end to the, beam B(see Fig. 1), which is fulcrun'ied on the plate C, fastened to thebracket D which in turn is The bracket B. is secured to one end of thebeam andthe balance ball adjustably mounted therein.

The counterpoise pendulum F is screw threaded and adjustably mounted onrod f securely attached in bracket 7, which is secured in turn to beamB, and as illustrated in Fig. 1, the pendulum is preferably secured tothat elongated load supporting element B near the fulcrunrpoint and ismounted at an inclination tomthe vertical,

but an important feature of this improve directly secured, thesupporting element bemg capable of being directly connected to theindicator hand at its opposite end.

Referring to the connections to-the indicator hand, there is employed arack rod G (Figs. 1 and 4) connected to beam B by the arm H (see Figs. 3and 1) in the usual and approved manner. This rack rod G has the rack Lat its upper end, engaging pinion'J on the pinion shaft i.

This shaft K is pivotally mounted in bearings at the ends, the outer endhaving its bearing in cup bearing L (Fig. 7 which bearing is seated inthe plate M which is secured to bracket or rib N, projecting from thestationary casing of the machine, and the inner end of the shaft K issupported in the cup bearing 0, seated in bracket N, which is preferablyformed integral with rib N (Figs. 7 and Q, is the indicator hand securedto the pinion shaft K" and same cooperates with the dial B.

As clearly appears from Fig. 1, the dial R has indicating numbersextending partially around its face, leaving an unmarked space on themargin, and by reason of the construction here employed, it is notnecessary that the indicator hand make a complete revolution.Consequently the plate M is preferably located in the unmarked spacewhere its connections to bracket N will not interfere with the propermovement of the indicator hand.

It therefore appears that there is here disclosed an indicator shaftsupported byouter and inner cup shaped bearings without in any wayinterfering with the proper movement of the indicator hand.

An indicating plate S (Fig. 1) cooper-' ates with an opening T toindicate integer amounts of the load on the scale. This plate S" isadjustably connected to the cage V,

. which cage contains a number of counterpoises. The cageB is connectedat its bottom to a chain a (Fig. 5) which extdnds upwardly and isconnected at its upper end to a pinion or sheave b; the sheave beingsecured to the shaft 0, and in close proximity to the sheave '5. Thereis shown a ratchet wheel (5 also secured to the shaft 0, and the ratchetpawl e is ,pivotally mounted on the frame so that the end ofthe pawlnormally engages the teeth of the ratchet d and the outer end of thepawl e is' formed with a key so that by depressing the key the ratchet d.will be released, and the cage V will be allowed to drop and therebytransfer the poises from the cage to the pendant, as illustrated andexplained in the co-pending application of H. B. Osgood, Serial No.683157. There are also preferably employed dash pot it connected to thebeam, and the retarding cylin:

der g connected to the cage, so as to cushion the movements of thoseparts.

IV IV are guide rods for the movable cage V, and X is a support for theretarding cylinder 9 and the guide rods 7 IV.

Having thus described my invention, I

claim 1. In a weighing machine, the combination of an automaticpendulum, dial scale with a supplemental weighing scale normallydisconnected from the first mentioned scale, consisting of a movablesupport nortion of an automatic pendulum, dial scale with a supplementalweighing scale normally disconnected from the first mentioned scale,consistingof a movable support and a plurality of counter-balances onsaid support adapted to be deposited successively on the first mentionedscale, and manually operated means arranged to arrest said support at aplurality of points during its movements operated holding devices forsaid support cooperating therewith to permit the oper ator to apply onebv one the counterbalances until the required amount has been applied tothe first mentioned scale and indicating devices for indicating theamounts of counterbalance applied for the purpose specified.

4. In a weighing scale, the combination of a load supporting element, amain counterbalance for said element, a supplementalcounterbalancing-device comprising a. gravity-operated-cage and aplurality of poises normally supported thereon, a ratchet 'and pawldevice located in proximity to the cage, and a flexible chain forconnecting the cage to the ratchet whereby upon the release of the pawlthe ratchet will be operated by the downward movement of the cage totransmit the poises onto the load supporting element,

for the purpose specified.

In testimony whereof, I have hereunto set my hand this 21st day ofSeptember 1912.

LOUIS A. OSGOOD.
